V AHeretofore, it has been proposed to hingedly connect a glass panel or the like to a win- A further object is to furnish a- 'ventilator bracket" including a bearing plate provided y .with a stop lug which will :function to limit the swingingmovement of, the panel toward the sash.

Another object isto provide a stamped y sheet: metal ventilatorbracket including a v channel portion designed to grip an edge of the ventilating panel, one sidel of the channel portion being stamped out to furnish a slotted y guide that cooperates with the swinging arm of the bracket.V

with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompointed out in the appended claims. y Referring to the drawing,

Fig. 1 is an velevation of a portion of a window frame and ventilator, the latter being provided with the improved bracket.v

Fig. 8 yis a. sectional view thereofl taken onA line 8-8 of Fig. 7. Y l A Y In the drawing, 10V designatesa .window frame, and 11 a lower sash` shdably mounted In accordance each .side of the wmdowtrame is Vprovided a front elevation ofa modificawith the present invention,

on its inner surface,`just above the sill 12, with abearing plate 13, which isof angularcon-y struction to provide a verticalstop lug 111..

An arm 16 is pivotally mounted on the plate 13 by any suitable.fastening means, but it is preferred to employ a screw 17 for this purpose, so that the screw not only functions as a pivot pin,`but. also actsto fasten `the parts 13 and 16 to the window frame. f

As best (shown, in Fig. 5, each arm l16 is provided at itslouter endv with a rigidly connectedfscrew A18 whichpasses through a 'slot 19 that formed in a wing 2O which is integral with a channel-shaped part 21. This part has converging side walls 22 and 23, 4and linmanufacturing .the improved bracket, the

wing l2O is stampedor cut from the wall 22, thereby leaving an opening'Ql.

As they channel-shaped part and its wing 2O` are* formed of sheety metal, it will be ap-y preciated that theextremities of the walls 22 and 23, may be pushed toward one another, so as to' cause the extremities to'grip an end ot' .a `Ventilatingppanel. This panel may be of anysuitable rigid materia-l, either transparent, translucent or i opaque, but. it `is prefer-red ,to makethe same 'of'glass y thumb nut 26 engages thescrew 18, and ,acts to clamp'the `wing20 to thearm 16, so

zthat the panel may be held in anydesiredposition of adjustment. c In Fig.3,V inlfull lines, i, the. bracketl is ShyOWnat the inner limit or" its inovefmelnt, ,whilefin dotted lines, it is shown y'e' ngag'g'ing fthe stop lug- 111, which limits the forward movement'of the panel.

` v.As'lckast shown yin Figs., v1 andf 3,the lower portion kof each ed, it Will be obviousv that asimilar bracket is'V used at the opposite endl of the panel 251 wWith a construction of this character, the brackets: may-be; sold separately a; ha-rd;-

vvare, store; orv the like, and the purchaser can then use With the same, a panel of any suitable material. Y

It Will be manifest that the present bracket is of simple and inexpensive corr-struction, and is one which is notliable to etv out of order in use. i Besides, it may be attached to a Window frame and may be adj usted by'all unskilled person.

From the foregoing, itis believedl that the construction, and advantages of the invention mayl be readily understood, and it is apparent that changes may be made in the details disclosed, Without departing from the spirit of the invention, as expressed in the claims.

In the modified form of Figs. 7 and 8;', the Wing 20 is Welded or brazed to the Wall 22 and provided With a slot 19 as in the preferred' form permitting the use of a rolled channel bar comprising Walls 21 2Q and 23.

What I claim and desire to secure by Letters Patent is:

l. A Windovs7 ventilator bracket, comprising a channel-shaped member having a slot extending parallel to the channel, and apivotally mounted arm having a fastening device slidably mounted in said slot.

2. A Window ventilator bracket comprising a channel-shaped member provided at one end with means for pivotally connecting the Y e same to a Window frame, said member having an elongated slot extending parallel to the channel, a pivotpin adj ustably mounted in the slot, an arm having one of its ends connected to the pivot pin, and means for pivotally connecting the other end of said arm to a Window frame. Y

3. A Window ventilator bracket including a channel-shaped member made up of a Web and opposite side Walls, means for pivotally connecting said member to a window frame, one of said Walls being cut to provide a slotted tonguek arranged in substantially the same plane as' the Web.

4. A Windowv ventilator bracket including a channel-shapedmember made up of a Web and opposite side ivalls', means for pivotally ,connecti'ng said member to a Windoiv frame,

one of said walls being cut to provide a slotted tongue arranged in substantially the same plane as the web, a pvot pin passing through said Slot, an arm ccnnected 'to the pivot pm,

and means for pivotally conjne'c"tingv said arm to, a window iframe.L e c.

5. A finden ventilator bracket including a channel-shaped member made up of a Web and opposite side Walls, means for pivotally connecting said member to a Window frame, one of said Walls being cut to provide a slotted tongue arranged in substantially the same plane as the web, a pivot' pinl` passing through said slot, an arm connected to the pivot pin, means for pivotally connecting said amianto a-Window tra-me,l` and a stop lug connected to the last, mentioned means for limiting the movement-of saidmember in. one

direction.

6. A Window Ventilator bracket, comprising. channel-shaped member provided at one end with means for pivotally connectingl the membertoa window frame, said channelshaped member includingv a Web and opposite' side Walls, a Wing'-r rigidly united with said member, arranged in; substantially the same plane als the web,J provided with. a slot positioned parallel to the channel, a pivot pin passing through' said slot, an arm corr nected to sai'd pivot pin, and means for pivotallly connecting the armto a Window frame.

7'. In a ventilator, a bracket comprising a channel-shaped member provided at one end with means for pivotally connectingthe same to a Window frame, said member includin'gy al web and opposite side Walls, one of said Walls'beilng out to provide a Wing po-. sitioned in the same plane as the web, vsaid Wing having an elongated slot arranged parallel to the channel-shaped member, an arm, a threaded fastening including a portion eX- tending through said slot, and means for pivotally connecting said arm to a Window frame. n

In testimony whereof I afli-X- my signature.
